The voltage in a certain circuit is given by v = -10e-t sin(224t), t in milliseconds and v in volts. how fast is the voltage changing at t = 4 ms? use radian mode

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
